ZSFM200-16DEP-F diaphragm deluge alarm valve is specially developed for super-large industrial fire fighting scenarios. It adopts DN200 large-caliber ductile iron valve body, suitable for high-pressure water supply system, covers an area of up to 3,500 square meters, and meets the fire fighting needs of flammable and explosive areas and super-large areas in industries such as petrochemical, electric power, and transportation. Its core function is to achieve rapid response by controlling the pressure change of the chamber. When the fire signal is triggered, the valve opens immediately and releases high-pressure water flow instantly, meeting the fire fighting requirements of NFPA 13 standard for high-risk places.
